ROLLER SIDE BEARING.

To all whom it may concern:

Be it known that I, PETER N. MoonE, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Visconsin, have invented certam new and useful Improvements in Roller Side Bearings; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention consists in what is herein particularly set forth with reference to the accompanying drawings and pointed out in claims of this specification, its object being to provide simple, economical and eflicient roller side bearings applicable to railwaycar trucks in opposition to car-bodies thereon, provision being had for travel of the rollers, under pressure, on a supporting surface in either of two directions from their' normal position to which they have automatic return when the pressure is removed; said roller side bearings being especially designed for use in connection with sidebearing bridges of railway passenger-car trucks to which they may be readily applied at small expense.

Figure 1 of the drawings represents a side elevation of a roller side bearing in accordance with my invention partly broken away and applied in connection with a side bearing bridge of a passenger-car truck; Fig. 2, a partly transverse central section view of the parts shown in Fig. 1, and Fig. 3, a plan view, partly in horizontal section, of the roller side bearing and truck bridge.

Referring by numerals to the drawings, 4 indicates a side bearing bridge of a railway passenger-car truck, and 5 the wear-plate with which the bridge is ordinarily provided, this plate being extended beyond the sides of the bridge. Supported in connection with the bridge is a bolt G that extends through a pair of fianged pivot-sleeves 7, and a nut 8 is run on the bolt to oppose one of the sleeves, the other sleeve being opposed by the head of the bolt. The bolt is herein shown as extending through the bridge, but it may be otherwise supported in connection with the same or instead of said bolt and sleeves thereon other provision may be had for pivots laterally of said bridge.

Each of the pivot-sleeves herein shown extends through a vertical slot 9 in a hanger 10 having pivotal suspension with an angular plate 11 of a preferably separable carriage-frame, and a preferably cylindrical weight 12 is horizontally suspended on a bolt. 13 engaging the lower ends of the hangers and having a nut 14.- run thereon.

Each plate of the carriage-frame is pro vided with lower inwardly extending end flanges 15 longitudinally thereof, and these flanges project under the plate 5 to limit upward play of said frame. Mounted in the frameto run on the plate 5 or other opposing surface are bearing-rollers 16 that oppose a car-body ora wear-plate attached thereto, such a body and plate being indicated by dotted lines in Fig. 1. The plates 11 of the carriage-frame are preferably provided with inner studs 17 that engage the rollers 1G, the center studs being bored for the passage of a bolt or rivet 18 that also engages said plates. Other bolts or rivets 19 are employed to fasten the ends of the plates of the carriage-frame together.

Each of the hangers 10 is preferably provided with a pivot-stud 2O that extends through an eye provided for same in a side plate 11 of the carriage, anda split-key 21 is shown extending through the end of each stud beyond the adjacent plate. The upper end of each hanger is preferably tape-red and the inner ends of the plate iianges 15 are beveled to match the taper of the opposing hangers.

To limit travel of the carriage in either direction from normal position, the bridge 1 is provided with stops, and to afford a sufliciency of such travel, the lower corners of the plates 11 of said carriage are angularly notched opposite said stops. The stops'herein shown are nuts 22 on bolts 23 extending through the bridge 4, spacing-washers 2a being employed on the bolts between the said bridge and nuts.

When the carriage has travel, in either direction from normal position, under pres-` sure upon the bearing-rollers 16, the hangers l0 with the weight 12 have sway in the opposite direction and a lift in proportion to the sway, the combined movement being a result of the slot engagement of each hanger with a stationary pivot. When the pressure is removed, the weight 12 operates by gravity to automatically restore the carriage and parts therewith to normal position.

The construction and arrangement of parts herein shown and described constitute a practical form of my invention but in Y "Without departure Y from 1. A roller side matters of detail myk improved side rollerl bearing is susceptible of indefinite variation the scopeof the claims herewith.Y ,j j

9. A railway car truck -bridge and a laterally projecting Wear-plate thereon, a roller side bearing comprising a carriage-frame rollers therein on the'Wear-plate, inner side flanges of the carriage-frame underlying the projections ofA said wear-plate, longitudinally slotted hangers in pivotal suspension from said carriage-frame, pivots arranged in connection with the bridge to engage the slots of the hangers, and a weight in connection With said hangers.
